of Letters Patent N 0. 414,550, dated November 5, 1889.

Application filed December 13, 1888. Serial No. 298,530 (No model.)

To all whom it may concern:

Be it known. that I, HERMAN KLINGLER, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented new and useful Improvements in Trusses, of which the followingis a specification.

This invention relates to that class of trusses which consist of ametallic band or belt to which the pads are yieldingly attached, so asto exert a continuous pressure on the rupture.

The object of my invention is to improve the construction of thetruss-belt and also to improve the construction of the truss-pad, so asto render the same easily adjustable to permit the pressure exerted bythe pad to be regulated.

The invention consists to these ends of the improvements which will behereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of thetruss with the pads removed. Fig. 2 is a detached elevation of thecentral front portion of the truss. Fig. 3 is a top plan view of one ofthe back plates of the truss. Fig. t is an elevation of the strapconnecting the rear ends of the belt. Fig. 5 is a longitudinal sectionof one of the pads and connecting parts detached from the belt. Figs. 6and '7 are similar views of the pads with the padding andspringoinitted, showing different adjustments of the pad-plate. Fig. Sisa vertical section of the screw-nut secured to the pad-plate. Fig. 9 isa section of the ball of the joint whereby the pad is connected with thebelt. Fig. 10 is a horizontal section of the socket of said joint. Figs.11 and 12 are views of the wrench and lever whereby the parts areadjusted.

Like letters of reference refer to like parts in the several figures.

The belt of the truss consists of two springfront ends by a connectingbar or piece A, and at their rear ends by a detachable leather. strap E,or other fastening.

D D represent the back plates, which are movably attached to the rearportion of the truss-belt in any suitable manner, so as to accommodatethemselves to the motions of the body of the wearer. In the constructionwith perforated cylindrical lugs or shanks C, Fig; 3, through which theends of the bows B 13' pass, and they are held against lengthwisemovement on the bows by set-screws c, which proj ect into annulargrooves o 0' (shown by dotted lines in Fig. 1) in the bows, so as topermit the back plates to rock on the bows. The central connecting-bar Ais provided at opposite ends with sockets, in which the front ends ofthe bows B B are secured by pins or rivets b b b b or otherwise. Thisforms a strong connection having no projecting parts. The centralportion of the connecting-piece A is curved, as shown, so as to properlyconform to the shape of the pelvis-bone. The bar A is provided onopposite sides of its central curve with longitudinal slots a a, whichreceive the attaching shank or screw of the truss-pads.

L represents the rigid pad-plate, to which the cushion. of the pad issecured by means of a clamping-plate M, attached to the rear side of thepad-plate by screws Z Z. These screws pass through space-blocks NN,arranged between the plates M L, as represented in Fig. 5. The edge ofthe facingcloth of the pad is stretched over the edge of the pad-plateL, and is clamped between the pad-plate and the clamping-plate M. Uponloosening the clamping-plate H the facingcloth can be removed andcleaned or a new cloth substituted therefor. The pad is attached to thetruss-belt by a ball-and-socketjoint, so as to have a free universalmovement, which shown in the drawings they are provided enables it toadapt itself to the motions of the wearers body.

F represents the socket of the joint, which is provided with ascrew-shank f, whereby the pad is attached to the belt, the shankpassing through the slot a of the center portion A, and being heldtherein by a washer g and nut h applied to the shank, the washer bearingagainst the outer side of the center piece. The slotted portions of thiscenter piece are preferably flattened, as shown,while the intermediatecentral portions and the .socketed end portions are preferably round incross=section. Upon loosening the nut h the pad may be moved in the slotto accurately adjust it to the rupture.

G is the ball seated in the socket F and provided with a threaded stemm, which engages in a cylindrical screw-nut H, secured centrally in thepad-plate L, as represented in Fig. 5. The screw-nut II is externallythreaded and secured in a threaded opening in the pad-plate by a nut71;, applied to the nut and bearing against the inner side of thepad-plate.

K represents a spiral spring surrounding the stem m and socket F andinterposed between the pad-plate L and a projecting annular flange orrim 2', formed on the socket F, the clamping-plate M being provided witha central opening through which the spring passes. The upper end of thespring K is clamped between the pad-plate L and a flange on thescrew-nut H, and the lower end of the spring is seated in an annulargroove 72, formed in the outer side of the flange of the socket F. Thespring K tends to press the pad outwardly against the rupture and exertsa continuous pressure on the pad. The cavity of the socket F iselongated, or made larger lengthwise than the ball G, as shown in Figs.6 and 7, so as to give the ball the necessary amount of play in thesocket to permit the pad to move inwardly and outwardly, as well asswivel in the socket. The ball G is provided with radial holes f, inwhich a lever or pin 0, Fig. 12, may be inserted for turning the ball inits socket. A circumferential slot J is formed in'the side of thecylindrical socket F for admitting this lever, as represented inFigs. 5,.6, '7, and 10. Upon turning the ball in one or the other direction, thescrew-nut H of the pad is caused to move inwardly or outwardly on thescrew-stern m of the ball and the pad caused to approach the socket F orrecede therefrom, thereby increasing or diminishing the tension of thespring K and regulating the pressure exerted by the pad. After adjustingthe pad the parts are held in position by a jam-nut d,

applied to the screw-stem m and bearing against the screw-nut H, asrepresented in Figs. 5, 6, and 7. The movement of the pad on the stem mis limited in one direction by the ball G and in the other by a head or'enlargement 6, Fig. 9, formed at the outer end of the stem m, whichbears against an offset or shoulder in the bore of the cylindricalscrew-nut H, said bore being smooth and larger than the diameter of thethreaded opening of the nut, so as to receive said enlargement and'formthe offset, as represented in Figs. 5, 6, and 7.

turned to adjust the pad. After the adjustment is made the jam-nut isagain tightened.

The ball-and-socket joint gives the pad free dom of movement in alldirections, allowing it to accommodate itself to the rupture and to themotions of the body, and the spring renders the pad elastic andyielding, so as to exert a gentle continuous pressure on the rupture,and also limits the swiveling movement of the pad.

The adjusting device of the pad permits the tension of the spring to bereadily regulated to suit the conditions of the rupture and the comfortof the weaver.

I claimas my invention 1. The combination, with a pad provided on itsrear side with a screw-nut and a band or belt having a longitudinalslot, of a cylindrical socket provided with a shank which is adjustablysecured in the slot of the belt, a ball seated in said socket andprovided with a screw-threaded shank engaging with the screw-nut on thepad, whereby the pad can be adjusted toward and from the socket, and aspiral spring surrounding the ball and socket with one of its endssecured to a flange or rim formed on the socket and its opposite endbearing against the-rear side of the pad, substantially as 'set forth.

2. In a truss, the combination of the socket F, the ball G, mountedtherein andhaving a shank m, the screw-nut H, for receiving the end ofthe shank m, the plate L in which the nut is mounted, and a spiralspring K, encircling the shank m and held at one end between a flangeupon the nut H and the plate L and at the other end to a flange upon thesocket F, substantially as set forth.

3. In a truss, the combination, with a socket having a circumferentialslot, of a'ball seated therein having a screw-stem and provided withholes for turning it in its socket, a pad having a screw-nut fitted onsaid screw-stem, and a spiral spring interposed between the pad and aflange on said socket, substantially as set forth.
